Electrification is believed to be the most important engineering achievement of the 20th century. The use of the term “technology” has changed significantly over the last 200 years. English, which usually translates both terms as “technology. In 1937, the American sociologist Read Bain wrote that “technology includes all tools, machines, utensils, weapons, instruments, housing, clothing, communicating and transporting devices and the skills by which we produce and use them.

When combined with another term, such as “medical technology” or “space technology,” it refers to the state of the respective field’s knowledge and tools. Technology can be viewed as an activity that forms or changes culture. Additionally, technology is the application of math, science, and the arts for the benefit of life as it is known. The distinction between science, engineering, and technology is not always clear.

The exact relations between science and technology in particular have been debated by scientists, historians, and policymakers in the late 20th century, in part because the debate can inform the funding of basic and applied science. United States that technology was simply “applied science” and that to fund basic science was to reap technological results in due time. New products, new industries, and more jobs require continuous additions to knowledge of the laws of nature This essential new knowledge can be obtained only through basic scientific research. The issue remains contentious, though most analysts resist the model that technology simply is a result of scientific research.

But rather as an uneven tendency to “percolate” outwards, that we see no evidence of other civilizations.

Meanwhile, humans were learning to harness other forms of energy. Nile boat dating to the 8th millennium BCE. Estimates on when this may have occurred range from 5500 to 3000 BCE with most experts putting it closer to 4000 BCE.

More recently, the oldest-known wooden wheel in the world was found in the Ljubljana marshes of Slovenia. The invention of the wheel revolutionized trade and war.

A bathtub virtually identical to modern ones was unearthed at the Palace of Knossos.
